A woman spent two thirds of her money she lost two thirds the remainder and then had $4 left how much money did she start with

Lisa [10]

Answer

Find out how much money did she start with.

To proof

let us assume that the money she had be x.

As given

woman spent two thirds of her money

$Money\ spent = \frac{2x}{3}$

Money she had after spent two thirds of her money = Total money - money spent

$= x - \frac{2x}{3}$

$= \frac{1x}{3}$

As given she lost two thirds the remainder

$=\frac{2}{3}\times ( money\ she\ had\ after\ spending\ two\ thirds\ of\ her\ money)$

$= \frac{2}{3} \times\frac{1x}{3}$

we get

$=\frac{2x}{9}$

Money she had after lost two thirds the remainder = Money she had after spent two thirds of her money - she lost two thirds the remainder

$= \frac{1x}{3} - \frac{2x}{9}$

$= \frac{1x}{9}$

As given

she had $4 left

thus

$\frac{1x}{9} = 4$

x = $36

she start with $36.

Hence proved

A publishing company is going to have 24,000 books printed. There are between 3 and 4 books out of ever 3,000 that will have a p

vaieri [72.5K]

Answer:

C. 31

Step-by-step explanation:

3000 there are 3-4 errors

If we first divide 24,000 by 3,000, will get 8

then since there a error for each 3,000 books, we do 8 x 4 = 32 and 8 x 3 = 24

32 (8 x 4) the max amount of printing errors

24 (8 x 3) the minimum amount of printing errors

So we should expect 24-32 printing errors

Only answer between the numbers is c. 31

Solve this inequality: 3q + 11 + 8q > 99.

IrinaVladis [17]

3q + 11 + 8q > 99

Simplify

11q + 11 > 99

Subtract 11 on both sides

11q + 11 - 11 > 99 - 11
11q > 88

Divide 11 on both sides.

q > 8

Your final answer is C. q > 8.
